Short Answer:
18. Explain Mendel’s pea plant experiment.
19. Explain Mendel’s contributions to the study of genetics.
20. Set up the Punnett squares for each cross, give the genotypic and phenotypic ratios of the offspring, and answer the question asked if purple flowers (P) are dominant to
white flowers (p).
a. What would be the chances of having an offspring with white flowers if you cross a heterozygous purple plant with a white plant?
b. What would be the chances of having a hybrid offspring if you crossed a heterozygous plant with a heterozygous plant?
c. What would be the chances of having an offspring with white flowers if you cross a homozygous purple plant with a heterozygous plant?
21. Explain what Punnett squares and chromosomes have to do with each other.
22. Explain the relationship between DNA, chromosomes, genes, and alleles.
